It looks like Taylor Kitsch wears Ray-Ban RB4165 Justin sunglasses in the 2017 movie Only The Brave, although a better image needed to confirm.

The Wayfarer style Ray-Ban Justin sunglasses have a matte black frame and Ray-Ban logo on the temples and lens. 

The Ray-Ban Justin sunglasses are available online at the Ray-Ban website or on Amazon (note that there are many colors and different sizes available for this model).

Taylor Kitsch plays firefighter Chris MacKenzie in Only The Brave (Granite Mountain), a film based on the elite crew of firefighters who battled the Yarnell Hill Fire, a wildfire in Yarnell, Arizona in June 2013 that claimed the lives of 19 members of their team.
